摘要：

Chaotic scattering at different projectile incident energies is studied for a model which involves a two-body van der Waals-type interaction. At higher energies one finds characteristics typical for hyperbolic chaotic scattering. For sufficiently low energies hyperbolic and nonhyperbolic chaotic scattering are found to coexist at the same energy. The mechanism of this coexistence is discussed in terms of the Lyapunov exponent and the fractal dimension. Arguments are put forward for an increase in the fractal dimension of the set of singularities leading to nonhyperbolic chaotic scattering.
